I shot a doe(100lbs) with my ML this weekend. I have been worried because the fist one i shot was a complete passthrough and I don't think it expanded. Well I bumped my powder up to 110 grn. The shot went in behind the last rib and came out in front of the opposite shoulder. She only went 20 yrds and collapsed. The damage was great. I have found a load I'm happy with. I'm shooting the 200grn shockwave pushed by 110 grn pyrodex. I get good groups out to 150. I havn't tried farther though. Good luck
